VTOL version about as likely as a dedicated export version.
Once the fc-31 got picked up for planaf new geb carrier fighter, the Chinese program j-35 or j-xy would mean export offers are limited. Why? Because while models are displayed, the priority customer has become the navy.
Export version would only be land based. J-35 is a carrier fighter. We haven't seen their land based version yet. It'll be many years before land based export version is on offer to the international market.
Any four distinct versions would be carrier, land based airforce, special mission e.g. twin seater for EW or ucav command, and then downgraded export version.
No way they wouldn't downgrade a 5th gen fighter. In terms of 5th gens reaching service it's f-22, f-35, j-20, su-57, and then j-35. Kfx is years later than j-35 since j-35 is ready in a few years and kfx hasn't made a first prototype test flight yet.
Amca, azm, tfx... All about a decade away at least. So why wouldn't they only offer a downgraded version for export. This isn't exporting a j-10. It'll be in a class of only four other fighters.
